We have written an in-house IDL code for measuring all of the six
described parameters of the selected sample of the non-AGN
galaxies. To obtain all needed input parameters we first run
SExtractor [1]} using the SDSS g-band images. When
necessary, the galaxy centre is
determined by minimizing ASYM [2]}, while the total
flux is defined as the one contained within 1.5 times the Petrosian
radius [3]} as measured by SExtractor.
